6. create an Ansible inventory file hosts with the below content:
localhost ansible_connection=local (this line is added so that Ansible can provision local machine)
testserver ansible_host=testsrv ansible_user=vagrant

(Assume ‘testsrv’ is the hostname you add in your /etc/hosts file, if you didn’t add a hostname for the target server, then use its ip instead)

7. Run the following command to make sure Ansible can talk to both local and remote machine
ansible all -i hosts -m ping
